CHOCOLATE-COOLING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 752,636, dated February 16, 1904. Application filed May 12, 1902. Serial No. 106 ,880- (No mode1.)

To all whom it may concern;

Be it known that I, EDWARD W.MULL, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented acertain new and useful Improvement in Chocolate-Cooling Mechanism, of which the following is aspecification.

My invention relates to chocolate-candy coolers of that class which are adapted for use in cooling and hardening chocolate candies; and the objects of my invention are to provide a cooling mechanism of this class of improved construction and arrangement of parts; to so construct my improved cooling mechanism as to insure a comparatively strong current of cold air being directed or discharged at the proper points; to provide in conjunction therewith an improved chocolatecontaining table or receptacle; to provide improved means for conveying candy-containing trays, and to produce other improvements the details of construction of which will be more fully pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanying drawings, in which 7 Figure 1 is aside elevation of my improved cooling device.- Fig. 2 is a central longitudinal section of the same enlarged from that shown in Fig. 1. Fig. 3 is a sectional view on line w w of Fig. 2. Fig. 4 is aplan view of the inner end portion of the elongated cooling and air-conducting chamber with the top removed. Fig. 5 is a sectional view through a portion of one of the upper flues of the airconduit or cooling-chamber taken on line 25 t of Fig. 4 and enlarged therefrom. Fig. 6 is a plan view of a portion of the work and chocolate-containing table, and Fig. 7 is a transverse section on line 2 2 of Fig. 1.

Similar numerals I refer to similar parts throughout the several views.

In carrying out the present invention it is designed to direct currents of cold air against the candies to cool the chocolate thereon, and therefore I employ any suitable form of aircooling or refrigerating deviceas, for instance, a box or casing, indicated at 1, having a pipe-coil 5 therein, which is designed to be embedded within ice or other suitable cooling 5 medium, with one end piercing the adjacent wall of the box and connected to a suitable power-driven fan 34, while its opposite end also pierces one wall of the box for communication with an air-conducting device, which will be hereinafter described. Connecting with the rear side of the box 1 is a comparatively long horizontally-arranged housing or casing 8, which is formed in its upper portion and on opposite sides with flues 9, which extend throughout the length of said casing or housing. Between these flues 9 and connecting therewith through the medium of air-openings 10 is formed a central upper flue 11, the bottom plate of which is formed with openings 12, which lead into the main passage 13 of said casing. The casing 8 is provided on its sides at intervals with doorways leading into the main air-passage 13, which are adapted to be closed by suitable hinged doors 14;. The casing or housing Sis supported by means of suitable legs or supports 15, which bear upon the upper side of a horizontal work-table 16, this work-table having under side supports 17 and having its upper side recessed to provide a longitudinal chocolate-receptacle 18, the latter having laterally-extending branch recesses 19. (See Fig. 6.) Leading downward from the oppdsitely-located side flues 9 of the easing 8 are comparatively small air-pipes 20, these air-pipes being arranged at desirable intervals and extendingto within close proximity of the work-table 16, As indicated in the drawings, these air-pipes are provided with angular-terminations.

In order to control the passage of air from the side flues 9 to the central flue 11, I provide on the outer sides of said central flue horizontally-arranged damper-plates 21,these damper-plates being provided at intervals with openings 22. (See Fig. 5.) In order to move these damper-plates to positions which will insure the openings 22 thereof registering.

with the openings 10 or to positions which will insure the closing of said openings 10, I

provide each of the damper-plates with an out wardly-extending operating-rod 23, the inner end of which is provided with a short crankarm 24:, which is pivotally connected with said damper-plate.

Journaled beneath the rear and forward ends of the housing or casing 1 are transverse shafts and 26, over which runs horizontally an endless carrier apron or belt 27 The shaft 25 is provided with a belt-wheel 28, which through a belt 29 is connected with a-wheel 30 on a counter-shaft 31, this shaft being connected, through a belt 32,with a main operating-shaft 33, which is rotated from any suitable source of power. That portion ofthe pipe 5 which is in front of the box 1 is connected with a suitably-driven power-operated fan 34. Beneath the work-table 16 I preferably employ one or more steam-pipes 35, the heat from which is designed to keep in 'desired melted condition the chocolate contained within the receptacle 18 of said table.

In utilizing my invention the air which is blown by the fan 34 through the pipe 5 becomes thoroughly cooled during its passage through the various arms of said pipe which are contained within the boX, and from said pipe the air thus cooled passes into the flues 9 of the casing 8, this air-current-from the pipe being deflected into both of said flues by causing the pipe 5 to discharge against the converging end Walls of the central flue 11, these converging walls being indicated more clearly in Fig. 4 of the drawings. The airwhich is thus directed into the flues 9 may escape therefrom through the openings 10 into the central flue 11, the amount of air which is thus directed to said central flue being .controlled by the movement of the damper-plates 21. From the central flue the air may escape through the bottom openings 12 into the main passage 13. It will also be understood that a portion ofv the air which is forced, as described, into the parallel flues 9 may pass outward and downward through the pipes 20.

In utilizing my improved cooling mechanism for the purpose of cooling chocolate-dipped candies the candies are covered in the usual manner with the liquid chocolate contained in the receptacle 18 of the work-table and when thus treated are arranged one after the other upon a suitable tray,which rests upon the table 16 in such position that the cooled air escaping from an adjacent pipe 20 will come into contact with the candy and serve to cool and harden the chocolate thereon. A tray being thus filled with candies, one of the doors 1 1 may be opened and the tray inserted within the main passage 13 of the casing 8, where it may rest until the candies thereon are thoroughly cooled and the chocolate sufliciently hardened. From the interior of the casing 8 the chocolate-containing trays are removed and placed upon the continuous belt or apron 27 and carried thereby to a suitable receivingtable 36, arranged at the end of said traveling belt. It is obvious that when the air-discharging pipes 20 are not in use the open ends thereof may be corked or otherwise closed.

From the construction which I have herein shown and described it will be seen that rework-table, thereby permitting the chocolate-- dipped candies being cooled and hardened as fast as the same-are dipped.
